coefficient of performance उदाहरण वाक्य

In addition to this, the evaporation temperature of the working fluid is higher than the case for air, so in general the coefficient of performance is significantly higher.
:From your two temperatures you can work out the maximum possible COP using the equation at Coefficient of performance ( COP = Tcold / ( Thot-Tcold ) ).
The Coefficient of Performance ( COP ) will increase as the conditions become more extreme ( i . e ., more hot and humid for cooling and colder for heating ).
Heat is extracted from seawater ( from depth ) that is 8 to 9 �C all year round, giving an average coefficient of performance ( COP ) of about 3.15.
The so-called Coefficient Of Performance \ xi ( COP ) of coolers is defined as the ratio between the cooling power \ dot { Q } _ L and the compressor power " P ".

The HSPF is related to the non-dimensional Coefficient of Performance ( COP ) for a heat pump, which measures the ratio of heat energy delivered to electrical energy supplied, independently of the units used to measure energy.
The system has an average coefficient of performance ( COP ) of 3.0 which means 1 unit of electricity is combined with 2 units of heat from the seawater to provide 3 units of heat to the district heating circuit.
The EER is related to the coefficient of performance ( COP ) commonly used in thermodynamics, with the primary difference being that the COP of a cooling device is unit-less, because the numerator and denominator are expressed in the same units.
From an environmental viewpoint then, you are using the same amount of raw energy if you intall a gas heater in your home as a ground source heat pump ( assuming coefficient of performance of 3 and power system efficiency of 30 % ).
The "'coefficient of performance "'or "'COP "'( sometimes CP or CoP ) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work required.
